Props to whoever thought up this contest, I think it will be awesome. I've had a blast checking out everyone else's little Pokémon, so now you have a chance to see mine. My rival is none other than the talented Brickunion758. Ironically we built the same Pokémon, Crawdaunt, proving that great minds think alike... anyways may the best trainer win!

Trainer Mike stands at the edge of the community pool, Pokéball in hand, and the RBY battle theme playing on the boom box. "Go, Neptune!"
Neptune splashes into the pool, ready for action. This Lapras was encountered by Mike in the ocean near Route 25, and proves useful when crossing the seas or impressing the ladies is necessary. But if he isn't enough....
"Lobstrosity! Knock 'em out!" Lobstrosity is a spiteful Crawdaunt recieved in a trade. His cross type of Water and Dark makes him a powerful ally. I understand this guy is a little too tall but that was the only way I could fit all the details.
Who's team will win? Anyways I look forward to seeing what everyone comes up with in the next round!

Excellent build! Both of your Crawdaunts were awesome, so it really came down to your second Pokemon. Luckily for you, that Lapras blew your opponent's Tentacool out of the water (no pun intended). You've got my vote!
